Investing involves risk; principal loss is possible. There is no
guarantee the Fund’s investment objectives will be achieved. This ETF
seeks to generally track the investment results of an index; however the
Fund may underperform, outperform or be more volatile than the
referenced index. This Fund invests in REITS and real estate companies.
The real estate industry is greatly affected by economic
downturns or by changes in real estate values, rents, property taxes,
interest rates, tax treatment, regulations, or the legal structure of
the REIT. The value of equity securities may decline
significantly over short or extended periods of time. The Fund’s assets
will generally be concentrated in the securities of issuers in
the real estate sector, and, accordingly, the Fund may be adversely
affected by the performance of those securities, may be subject to
increased price volatility and may be more susceptible to adverse
economic, market, political or regulatory occurrences affecting that
industry. These and other risk considerations, such as interest rate,
non-diversification, and smaller company risks, are described in detail
in the Fund’s prospectus.

Before investing, carefully consider fund investment objectives,
risks, charges and expenses. For this and other information that should
be read carefully, please request a prospectus or summary prospectus
from your financial advisor or Nuveen at 800-257-8787 or visit www.nuveen.com.
